Sometimes the tires go when you do a long burnout. Sometimes it’s more serious.
The following video comes from Australia, where they’re certainly no strangers to big clouds of tire smoke. But this particular burnout also featured a different kind of smoke, a kind which you generally don’t want to see. The driver probably should have noticed that something was definitely going wrong, but he decided to just keep his foot in it anyway until the engine puked up all of its fluids and some pretty important-looking metal bits.
It’s safe to say that engine is toast. Maybe he’ll be lucky and salvage the big blower.
